Answers

Answer 1

It’s proportional it’s equation it y=3.5x

Answer 2

Answer:

Yes it is proportional (Equation: y=3.5x)

Step-by-step explanation:

Notice that there is a constant change in y and a constant change in x. But by how much? Given the last point (13,45.5) we can see that 13-12=1 and 45.5-42=3.5 so that means as x increases by 1, y always increases by 3.5, making the relationship proportional. You can also write the equation y=3.5x to show this

Which equation can be used to solve for x in the parallelogram below?

A) 3x-12=6x+12

B) (7x-8)+(6x+12)=90

C) 3x-12=2x+8

D) (7x-8)+(6x+12)=180

Answers

Answer:

B. (3x - 12)° = (2x + 8)°

Step-by-step explanation:

This equation can be used to solve x.

3x - 12 = 2x + 8

3x - 2x = 12 + 8

x = 20°

-------------------------------------------------------------------

Verification:

3(20) - 12 = 2(20) + 8

60 - 12 = 40 + 8

48° = 48°

Step-by-step explanation:

each bracelet takes 15 min

15*3=45

1 hour = 60 minutes..

In 1 hour she makes 4

In 2 hours (120 minutes) she makes 8

So in each hour she makes 4 ( 8 /2 = 4)

So In 3 hours she will make 3 x 4 = 12 bracelets

Autumn's family took a road trip to Mount Rushmore. Autumn fell asleep 39% of the way through the trip. If Autumn fell asleep after they had travelled 351 miles, what was the total length of the trip?

Answers

Answer:

900 miles long

Step-by-step explanation:

Given data

Le the total mile of the trip be x

Autumn fell asleep at 39% of the trip, which is equal to 351 miles

=39/100*x= 351

0.39x= 351

divide both sides by 0.39

x= 351/0.39

x= 900 miles

Hence the trip is 900 miles long

*. Your club is trying to raise money for a trip to Atlanta. They purchase boxes of candy to help fund the trip. Each box contains 60 candy bars. Each box costs $45. How much money does the club have to charge for each candy bar to make a profit of $39 per box? A. $2.60 per candy bar B. $1.25 per candy bar C. $1.40 per candy bar D. $2.69 per candy bar

Answers

The school has to sell each box for $40 to make a profit of $10 per box because each box costs $30.
There are 50 candy bars per box.
$40/50=$0.80 per candy bar
It's costing the school $30/50=$0.60 per candy bar to buy.
The school sells each candy bar for $0.80, making a profit of $0.20 per candy bar.
50*$0.20=$10.00

Answers

Answer:

5^2+h^2=12^2, the answer would be ~10.97 ft.

Step-by-step explanation:

I would use the Pythagorean theorem to solve this problem. Put in the things that you know, so in this image we are given one of the legs and the hypotenuse of the triangle.

Pythagorean theorem is :

a^2+b^2=c^2 with a and b being the legs and c being the hypotenuse.

Once you plug in the hypotenuse and one of the legs, solve for the other leg by subtracting a^2 (5^2) from 12^2 (c^2), which will give you 119, and then take the square root of 119 and you will get your answer.

do 252/448 and 36/64 form a proportion?

Answers

Answer:

252/448 and 36/64 form a proportion

Step-by-step explanation:

The easiest way to do this is to let 252/448 = 36/64

Then cross multiply to get 252(64) = 36(448)

16128 = 16128

Since the two products are equal, then 252/448 and 36/64 form a proportion. If the the two products were unequal, then the two fractions would NOT form a proportion.

Answer:

r=1, h=9

r=2, h=2.25

r=5, h=0.36

r=12, h=0.0625

r=r, h=9/r²

Step-by-step explanation:

Volume of a cone = πr²h/3

3π=πr²h/3

r²h=9

when r=1?

r²h=9

1²h=9

h=9

when r=2?

r²h=9

2²h=9

4h=9

h=2.25

when r=5?

r²h=9

5²h=9

25h=9

h=0.36

when r=12?

r²h=9

12²h=9

144h=9

h=0.0625

when r=r?

r²h=9

h=9/r²

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

Volume

Volume is the amount of space that is occupied by a three dimensional object.

The volume of a cone (V) is given by:

V = (1/3)πr²h

Where r is the radius and h is the height.

For a radius of 1:

3π = (1/3)π*(1)² * h

h = 9

For a radius of 2:

3π = (1/3)π*(2)² * h

h = 2.25

For a radius of 5:

3π = (1/3)π*(5)² * h

h = 0.36

For a radius of 12:

3π = (1/3)π*(12)² * h

h = 0.02

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.
